From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Immutable Distro Opinions (www.linuxfordevices.com)

I recently took up Bazzite from mint and I love it! After using it for a few days I found out it was an immutable distro, after looking into what that is I thought it was a great idea. I love the idea of getting a fresh image for every update, I think for businesses/ less tech savvy people it adds another layer of protection from self harm because you can't mess with the root without extra steps.

For anyone who isn't familiar with immutable distros I attached a picture of mutable vs immutable, I don't want to describe it because I am still learning.

My question is: what does the community think of it?

Do the downsides outweigh the benefits or vice versa?

Could this help Linux reach more mainstream audiences?

Any other input would be appreciated!

Well it's a bit confusing. On Guix' wiki General features you can read:

Guix keeps track of these references automatically so that installed packages can be garbage collected when no other package depends on them - at the cost of greater storage requirements, all upgrades in Guix are guaranteed to be both atomic and can be rolled back.

The roll-back feature of Guix is inherited from the design of Nix and is rarely found in other operating systems, since it requires an unorthodox approach to how the system should function (see MicroOS).

And then on its wiki Guix System (operating system) Roll-back you can read:

This is accomplished by a combination of Guix's functional package manager, which treats each package and system configuration as an immutable and reproducible entity,[58] and the generation system which maintains a history of system configurations as "generations."

So the system configurations on a Guix system are actually immutable, as opposed to regular gnu+linux distributions, which can change the system configuration on the fly. What else is immutable on Guix, I can't tell, but at least you can not change its system configs. What is atomic is the upgrades.

I'm not sure, but as Guix borrowed these properties from Nix, I'd think this applies to Nix as well.

In other words, at least the Guix system has immutable components. And further, the system config which is immutable, is also declarative. Combining those two things might be intimidating, since it's not like on the fly one can go and change the system config, which might be required when debugging some misbehavior, and it's what most distros document, then one needs to learn about guile, and a bit about functional programming I guess or at least their basics... Deploying systems might take advantage of such declarative configurations though...
